Your UFO software package is very impressive and a great help for meteor enthusiast.
Keep up the good work !

Firstly, I read the whole (english) forum, it was interesting, I learnt a lot from it.

Is there a possibility to I could add country borders to gmaps? (if it is but just manually or dot to dot isn't a problem I'm patient ) It will be clearer to see trajectories in the busy middle europe in UFOAnalyser.

1. modify map data
To be perfectly copyright free, the ground map data for UFO series
is generated by GMAP2 (private program that I made in 2003,
which reads only NASA SRTM30 data, make reduced color map, and compress it).

I am not sure now, but probably it may be possible to modify GMAP2 to
generate maps that display additional data in special color, if I can get
copyright free numerical border data.

2.modify UA2/UO2/....
modify UA2/UO2 to be able to overlay some numerical data on the map....

2 seems more useful. It can display not only border but coast line
or additional marks .....

Anyway numerical border data that is apparently copyright free (GNU GPL is not enough) is necessary. Can you make it?
If it is possible to make original border data and publish it as copyright free data, I will consider to add new functions to my program.

The data format may be something like below, series of points.
U_MAPADD.CSV ===================
format_id, mark_id, longitude(decimal in degree), latitude(decimal in degree)
MA01, 1,+359.9999,+89.9999
MA01, 1,-0.0,-89.9999
......

P.S.
As for R90bug, I remember, there is R91format that ignore time zone of running PC. Try replacing just "R90" to "R91"

1. You have to download a map (jpg, bmp etc.) with
- the requested lines
- coordinate grid
- as high resolution as you can find on the net

2. You have to calibrate this map
I used Oziexplorer demo version free to download from the net
It has limitation so, (you can use just 9 points to calibrate, but it's enough in general) if you can do it with another software then do. I've used this program from a long a time so I know it well...that's why I choosed it...

3. Patient work to add as many points as you can
Magnify the map for detailed view, I used 400% to work with.
A lots of clicking adding points along the borders. With Ozi, you can save into .pnt file, which is a txt format.

many thanks for this extension. It is very useful. I added more points to the central europe border lines (with interpolation from the existing data points, too lazy to enter the points manually) to make the borders better visible at high magnification.

There is a way to show double or triple or more observations about the same meteor in UFO-Orbit?

If I made the R91 input for it for the four different sites about the same meteor then UFOOrbit show just two of them... maybe the data quality is the best for this two, but I would like to see the other two anyway...or maybe the observation distance is bigger in that case...I don't know why UFOOrbit chose this two station but I'd like to see all of them...

I attached the R91 input files and the solution about only two stations.
